To 6577 whom it may concern:

Be it known that I, THOMAS E. MURRAY,

, a citizen of the United States, residing at New York, in. the county of New York and State of New York, have invented a certain new and useful Improvement in Outlet- Boxes for Protective Casings for Line Conductors, E which the following is a specificaticn.

The invention is an outlet box for protective casings for line conductors, and consists in the construction more particularly hereinafter set forth. I

In the accompanying draWingsFigurel is a-perspectire view of my device. Fig. 2 is a similar View of the cover of the outlet be): separately, Fig. 3 is a similar View of the-base portion of said outlet-b0X, with the' trough-shaped lower portions of the casing secured thereto.

In Fig. 1, a cover section of the casing is indicated by dotted lines.

Similar numbers of reference indicate like parts.

1, 2 are adjacent base sections of the protective casing. Each section has a flat bottom 3, and iongitudinal side flanges which are bent over outwardly to form double walls +2 and then outwardly again, as shown at 5, to form gutters. The said base sections are to be secured to the Wall or other support by any suitable means, and form a receiving trough -for the line conductors. They are provided with covers, as indicated by dotted lines in order to m: an any desired point on the g, the cover being removed, the adjacent sections may be separatedimo conz'iectcd, shown in Fig. 3, by screws 8 the sheet .metal base plate t of an outlet-box. Said base plate is polygonal in form and has at its corners upwardly turner "dly hooked flanges 10.

tion 9, and is provided with recesses 12 in opposite side flanges to fit upon said base sections, and with slits 13 in its corner flanges to receive the hooked over upper ends of flanges 10. In the upper side of the cover 11 is an opening provided with slotted lugs 14 for the attachment of any device to be connected in circuit to the line conductors,

When the casing covers are in place, the ends thereof abut against the outlet box, as indicated by dotted lines. in Fig. 1.

I claim:

1. An outlet box for protective casings for line conductors, comprising a bottom plate interposed between and connected to said casings, an inverted box-shaped cover receiving the ends of said casings in recesses in its side Walls, and means for connecting said cover to said bottom plate the said cover having an outlet opening for said line conductors in its top wall.

2. An outlet box for protective casings for line conductors, comprising a bottom plate interposed between and connected to said casings, an inverted box-shaped cover receiving the ends of said casings in recesses in its side Walls, and an outlet duct for said line conductors on the top Wall of said cover.

An outlet box for protective casings for line conductors, comprising a bottom plate interposed between and connected to said casings, an inverted box-shaped cover receiving the ends of said casings in recesses in its side Walls, and tongues on said bottom plate engaging openings in said cover:
